Abstract

A control system for a gas turbine engine (20) comprises a case structure (70), a clearance control ring (66) mounted for movement relative to the case structure (70), an outer air seal (64) mounted to the clearance control ring (66) and facing a first engine component (62), and a control and valve assembly (200) that receives flow from a flow input source (24). The control and valve assembly (200) is configured to direct flow into a first cavity (68) positioned radially between the case structure (70) and the outer air seal (64), and wherein the control and valve assembly (200) is configured to direct flow into a second cavity (208) positioned downstream of the first cavity (68) to interact with a second engine component (114).
